Flooded type water cooled screw chiller (PCB Control)
11
Large cooling capacity chillers have two truly independent refrigerant circuits, compact outline and
superior partial load efficiency. Besides, when one of the compressors breaks down, the other one
can work independently. So the chiller can provide much higher reliability and minimize the loss of
user.
Flooded-type evaporator
Evaporator is flooded type designed for 1MPa working pressure on the chillled water side (Higher
pressure vessels can be customized). Replaceable integral finned copper tubes are mechanically
bonded to steel tube sheets. The evaporator has been tested under
extreme conditions. The 20MM thickness insulation covers all low
temperature surfaces, including the evaporator, water boxes, oil
return lines, chilled water flow switch piping, etc.
Midea heat exchangers are designed by professional design
software and pass rigorous tests. Double-grooved holes at tube
support for tube expansion are designed to prevent leakage and
increase the durability of heat exchanger.
Condenser
Midea condenser has a specially designed baffle, in the entrance of condenser, to prevent direct
impingement of high-velocity refrigerant gas on tube surface and thus eliminate the related vibration
and noise. It has been tested under extreme conditions. Water side working pressure is designed
for 1.0Mpa (Higher pressure vessels can be customized).
Throttling device
Orifice baffle without moving parts can guarantee high reliability and it
cooperates with EXV

to throttle the high-pressure liquid
refrigerant from condenser to evaporator.EXV which is controlled by
EVD module provides high-precision adjustment and perfectly
matches the compressor load

Advanced oil system
As the diagram shown, the low
temperature and low pressure gas
enters the compressor through
suction port. Then refrigerant gas that
entered the compressor is
compressed to a high temperature
and high pressure gas and enters the
condenser to release heat to cooling
water. The condensed liquid passes
the throttling device, becomes the
